My, what nice trees you have. Yes yes, money doesn’t really grow on trees. But recent research from the Center for Urban Horticulture at the University of Washington points to the next best thing — that trees in business districts have a positive effect on consumer behavior.
The most recent version of Google Earth has added a nifty new 3D Trees feature!
In the first government-sponsored urban tree planting effort since the 1970s, Britain has committed £4.2m to plant one million trees by 2015. Declining rates of tree planting are the motivation for this new effort, which is being co-sponsored by Defra, Forestry Commission, Woodland Trust, Trees for Cities, Tree Council, and more.
For those of you who were at GreenBuild a couple of weeks ago, I hope it was a successful show and that you had the opportunity to learn and go to a bunch of the interesting sessions. But if you didn’t go, or just didn’t make it to our session, ASLA’s “The Dirt” blog has… More
